Comments on: Using ActiveRecord’s to_xml to produce custom xml including deep level associations

With the deep_xml method example, children aren’t wrapped in a tag, so I had to define the method like:

def deep_xml(builder=nil)
to_xml(:builder => builder) do |xml_builder|
xml_builder.children { |xml|
children.each{|child| child.deep_xml(xml)}
}
end
end

Glenn, this builder trick is exactly what I needed… but what about to_json? Does it support the same type of block/builder solution?

Good insight, but I have a related but somewhat different problem. With an ActiveRecord.find result (81 columns/fields – large number of records) I need to override the builder to format number values (commas and exactly 2 decimals [the DBF won't handle it] to print reports) before writing out to XML. I’ve spent hours in the blogosphere and forums and your post is the closest to on-point. I can readily do it in AS3 but I’m trying to shift as much work as possible to the Rails back-end — Flash times-out on me even with asynchronous processing. And I can’t seem to get my arms around xmlmarkup.rb. Do you know a place to point me?

Thanks for this, Glenn. I knew that this must be possible without overwriting ActiveRecord but hadn’t thought of passing the builder via a block. Saved me some time and effort :)
